Math: Area and Perimeter

We have learnt Area and Perimeter of squares and rectangles.
In P4, squares and rectangles are combined to form composite figures.
We are to find the Area and Perimeter of composite figures.

Summary:
Perimeter is the outline of the figure.
Perimeter of rectangle / square = Length + Breadth + Length + Breadth

Area is the space within the figure.
Area of rectangle / square = Length x Breadth
